To emphasize that although cystic pancreatic neoplasms are stated to make up only 10% of pancreatic cysts, this number may be significantly higher if patients who are misdiagnosed with pseudocysts are considered.
A small case series.
A tertiary-care centre.
A consecutive sample of three patients with cystic lesions of the tail of the pancreas seen between 1992 and 1994. All three were women ranging in age from 28 to 42 years. Two had been treated previously for pancreatic pseudocysts by cystenterostomy. None had a history of pancreatitis or alcohol abuse, and gallstones were not present on ultrasonography.
Distal pancreactectomy and splenectomy.
The excised specimens from the two patients treated initially elsewhere revealed mucinous cystadenoma with atypia in one and mucinous cystadenocarcinoma with invasion into stomach in the other. In the third patient, a cystic neuroendocrine tumour and two other intrapancreatic nodules of neuroendocrine tumour were found on pathological examination.
Pancreatic neoplasms may be misdiagnosed as pancreatic pseudocysts. In patients without a history or risk factors for pancreatitis, a cystic pancreatic mass is not necessarily a pseudocyst, and such patients should be considered for pancreatic resection.
强调尽管胰腺囊性肿瘤据称仅占胰腺囊肿的10%，但如果将被误诊为假性囊肿的患者考虑在内，这一数字可能会显著更高。
一个小型病例系列。
一家三级医疗中心。
1992年至1994年间连续收治的3例胰腺尾部囊性病变患者。3例均为女性，年龄在28至42岁之间。其中2例曾因胰腺假性囊肿接受过囊肿造瘘术治疗。均无胰腺炎或酗酒史，超声检查未发现胆结石。
胰体尾切除术和脾切除术。
最初在其他地方接受治疗的2例患者的切除标本，其中1例显示为非典型性黏液性囊腺瘤，另1例显示为黏液性囊腺癌并侵犯胃。在第3例患者中，病理检查发现一个囊性神经内分泌肿瘤和另外两个胰腺内神经内分泌肿瘤结节。
胰腺肿瘤可能被误诊为胰腺假性囊肿。对于没有胰腺炎病史或危险因素的患者，胰腺囊性肿块不一定是假性囊肿，此类患者应考虑行胰腺切除术。
